I know haha, but I like to be well informed before spending any time into learning C++, Blueprint and Unreal 4. I have bought 4 books about blueprint and unreal 4 and I’m going through any tutorial I can find on this website AND on youtube. So it’s not like I went straight to the legal stuff. 
Lie I said earlier, I just don’t want to be surprised by certain payment/legal stuff when I made the product and thinking of selling. That’s all…
